So I filed my claim for ptsd in beginning of 2018. Never had a medical diagnosis, I just uploaded all my paperwork and CAB and told the truth in my statemenr. No buddy letters or anything. Then left it alone, forgot about it actually. I was approved in november for 70%,now I am at 100. I see people post all the time about going to exams, nexus letters, etc. I never did an exam to get approved. Has anyone else heard of this?
